Abstract
Description
Technical Field
[0001] This utility model relates to the field of film winding machines, and in particular to an RO membrane winding machine with dustproof function. Background Technology
[0002] RO membranes (reverse osmosis membranes) are the core components of membrane separation technology and are widely used in water treatment (seawater desalination, drinking water purification, industrial wastewater reuse), food processing (juice concentration), pharmaceutical purification and other fields. Their product performance directly determines the filtration efficiency and service life of downstream equipment, and the membrane winding machine is a key piece of equipment in the RO membrane manufacturing process.
[0003] The core filtration function of RO membranes relies on their dense separation layer with extremely small pores. During the RO membrane production process, if impurities such as dust, fibers, and tiny particles in the environment adhere to the membrane surface or embed themselves in the gaps between the membrane layers, they will directly block the membrane pores, leading to a decrease in membrane filtration performance. Existing membrane winding machines generally adopt a negative pressure dustproof structure, which is prone to allowing external dust to enter due to pressure differences. Its dust removal effect is difficult to meet the cleanliness requirements of RO membrane production and will still affect the quality of membrane elements. Therefore, we propose an RO membrane winding machine with dustproof function to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an RO membrane winding machine with dustproof function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An RO membrane winding machine with dustproof function includes a housing. A dust cover is hinged to the upper surface of the housing by a pin. A vent pipe is fixedly connected to the outer surface of the dust cover. A centrifugal fan is installed inside the vent pipe. A filter chamber is fixedly connected to one end of the vent pipe. Two first slides are opened on the inner wall of the filter chamber. A first slider is slidably connected inside each of the two first slides. A filter box is fixedly connected between the two first sliders. A handle is installed on the outer surface of the filter box. Two filter screens are installed inside the filter box.
[0006] In a further embodiment, the inner wall of the box is rotatably connected to a receiving roller via a bearing, the outer surface of the box is fixedly connected to a fixing frame, the inside of the fixing frame is fixedly connected to a motor, and the output end of the motor is fixedly connected to one end of the receiving roller.
[0007] In a further embodiment, the inner wall of the box has two second slides, and the interior of each of the two second slides is slidably connected to a second slider. The two second sliders are rotatably connected to a feeding roller via a bearing.
[0008] In a further embodiment, a first pressure sensor is installed on the outer surface of the housing, and a second pressure sensor is installed on the inner wall of the housing.
[0009] In a further embodiment, an exhaust vent is provided on the outer surface of the housing, and a controller is installed on the outer surface of the housing.
[0010] In a further embodiment, a flow equalization plate is fixedly connected to the inner wall of the dust cover, a clamping rod is fixedly connected to the outer surface of the dust cover, and a sealing strip is installed on the outer surface of the dust cover. In a further embodiment, a hinge is fixedly connected to the outer surface of the housing, and a limiting plate is hinged inside the hinge. The outer surface of the limiting plate is provided with a locking hole that matches the locking rod.
[0011] In a further embodiment, four support legs are fixedly connected to the bottom surface of the box, and anti-slip pads are installed on the bottom surface of each of the four support legs.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This device uses an intake filtration system consisting of a centrifugal fan, air duct, filter chamber, and filter box to perform dual filtration on the air entering the chamber, effectively intercepting impurities such as dust, fibers, and fine particles. At the same time, the continuous input of clean air creates a slightly positive pressure environment inside the chamber, preventing unfiltered external air from seeping in through gaps. By cutting off the path for impurities to contact the RO membrane through both active filtration and pressure barrier, it avoids membrane pore blockage, ensures the integrity of the RO membrane separation layer and filtration performance, and solves the problem of existing negative pressure dustproof structures being prone to external dust entering due to pressure differences.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4In this utility model, an RO membrane winding machine with dustproof function includes a housing 2. A dust cover 3 is hinged to the upper surface of the housing 2 by a pin. A vent pipe 16 is fixedly connected to the outer surface of the dust cover 3. A centrifugal fan 15 is installed inside the vent pipe 16. A filter chamber 13 is fixedly connected to one end of the vent pipe 16. Two first slide rails 4 are opened on the inner wall of the filter chamber 13. A first slider 7 is slidably connected inside each of the two first slide rails 4. A filter box 6 is fixedly connected between the two first sliders 7. A handle 5 is installed on the outer surface of the filter box 6. Two filter screens 14 are installed inside the filter box 6. A first air pressure sensor 9 is installed on the outer surface of the housing 2. A second air pressure sensor 18 is installed on the inner wall of the housing 2. The first air pressure sensor 9 on the outer surface of the housing 2 monitors the external ambient air pressure in real time, and the second air pressure sensor 18 on the inner wall monitors the air pressure inside the housing in real time. The air pressure data of the two sensors are transmitted to a controller 10 on the outer surface of the housing 2. An exhaust hole 12 is opened on the outer surface of the housing 2. A controller 10 is installed on the outer surface of the housing 2. After the controller 10 is started, the centrifugal fan 15 installed inside the ventilation pipe 16 begins to work, drawing in external air into the ventilation pipe 16 and delivering it to the filter chamber 13. After entering the filter chamber 13, the air first flows through the filter box 6. The two filter screens 14 inside the filter box 6 will double-intercept the air, effectively filtering dust, fibers, small particles and other impurities, ensuring that the air entering the chamber 2 is clean. The clean air after double filtration is evenly distributed into the internal space of the chamber 2 through the flow equalization plate 17 fixedly connected to the inner wall of the dust cover 3. As clean air is continuously input, a slightly positive pressure environment is formed inside the chamber 2, which can prevent unfiltered external air from seeping in from the gap between the chamber 2 and the dust cover 3. At the same time, the exhaust holes 12 on the outer surface of the chamber 2 will discharge some air in real time to avoid excessive positive pressure inside the chamber and damage to the components, and maintain stable air pressure. The controller 10 analyzes the air pressure difference inside and outside the chamber 2. When the air pressure difference is abnormal, the controller 10 will issue a warning signal to remind the staff to maintain it in time and avoid the dustproof system failure affecting the quality of the RO membrane.
[0020] The inner wall of the housing 2 is rotatably connected to a take-up roller 21 via bearings. A fixing frame 23 is fixedly connected to the outer surface of the housing 2. A motor 24 is fixedly connected inside the fixing frame 23. The output end of the motor 24 is fixedly connected to one end of the take-up roller 21. Two second slide rails 19 are opened on the inner wall of the housing 2. A second slider 20 is slidably connected inside each of the two second slide rails 19. A feed roller 22 is rotatably connected between the two second sliders 20 via bearings. According to the size of the RO membrane raw material roll, the second sliders 20 at both ends of the feed roller 22 are pushed so that they slide in the two second slide rails 19 on the inner wall of the housing 2, which facilitates the pick-up of the feed roller 22. One end of the RO membrane raw material is fixed on the take-up roller 21. The motor 24 inside the fixing frame 23 on the outer surface of the housing 2 is started. The output end of the motor 24 drives the take-up roller 21 to rotate around the bearing. During the rotation, the take-up roller 21 evenly winds the RO membrane without manual intervention, which improves the film winding efficiency and avoids the introduction of external impurities by manual operation.
[0021] A flow equalization plate 17 is fixedly connected to the inner wall of the dust cover 3. A locking rod 28 is fixedly connected to the outer surface of the dust cover 3. A sealing strip 8 is installed on the outer surface of the dust cover 3. When the dust cover 3 is closed, the sealing strip 8 on its outer surface fills the gap between the dust cover 3 and the housing 2, further reducing the entry of external pollutants. Then, the limiting plate 26 inside the hinge 25 on the outer surface of the housing 2 is rotated, so that the locking hole 27 on the outer surface of the limiting plate 26 engages with the locking rod 28 on the outer surface of the dust cover 3, tightly fixing the dust cover 3 to the housing 2, preventing gaps from forming due to vibration during equipment operation. The outer surface of the housing 2 is fixedly connected with a hinge. The hinge 25 has an internal hinged limit plate 26. The outer surface of the limit plate 26 has a locking hole 27 that matches the locking rod 28. The bottom surface of the box 2 is fixedly connected to four support legs 11. The bottom surface of each of the four support legs 11 is equipped with an anti-slip pad 1. The four support legs 11 fixedly connected to the bottom surface of the box 2 provide stable support for the equipment and prevent the equipment from tilting. At the same time, the anti-slip pads 1 installed on the bottom surface of the support legs 11 increase the friction with the ground, reduce the vibration generated by the motor 24 during operation, and ensure the stability of the take-up roller 21 and the unload roller 22 when rotating, and further ensure the RO membrane winding accuracy.
[0022] The working principle of this utility model is as follows: When this device is in operation, first close the dust cover 3. The sealing strip 8 on its outer surface fills the gap between the cover and the housing 2. Rotate the limiting plate 26 inside the hinge 25 of the housing 2 so that the locking hole 27 of the limiting plate 26 engages with the locking rod 28 of the dust cover 3 to achieve a tight seal. After startup, the centrifugal fan 15 in the vent pipe 16 draws in external air, which is filtered by the filter box 6 in the filter chamber 13. The filter box 6 is slidably installed in the first slide rail 4 of the filter chamber 13 via the first slider 7. The two internal filter screens 14 double-intercept the air. Clean air is evenly delivered into the housing 2 through the flow equalization plate 17 on the inner wall of the dust cover 3, forming a slight positive pressure to prevent external impurities from seeping in. The exhaust port 12 outside the housing 2 balances the air pressure to prevent damage to components. The RO membrane raw material roll size is determined by pushing the second sliders 20 at both ends of the feeding roller 22, causing it to slide within the second slide rail 19 on the inner wall of the housing 2, fixing one end of the raw material onto the receiving roller 21. The motor 24 inside the outer fixing frame 23 of the housing 2 is then started, and the motor 24 drives the receiving roller 21 to rotate, achieving automated film winding. The first air pressure sensor 9 outside the housing 2 monitors the external air pressure, and the second air pressure sensor 18 on the inner wall monitors the internal air pressure. The data is transmitted to the controller 10. When the air pressure difference is abnormal, the controller 10 issues an early warning. The operator can pull out the filter box 6 through the handle 5 for maintenance. At the same time, the four support legs 11 on the bottom of the housing 2 and the bottom anti-slip pad 1 ensure the stability of the equipment, reduce the vibration interference of the motor 24, and ensure the film winding accuracy and dustproof effect.
